OK, then let's keep the current behavior.
If we stick with "undef means default", we should also consider to disallow
undef for Boolean and number arguments if there's no default.
That should be the current behavior for *all* arguments in the Perl bindings,
unless a change has gone through that I missed. Arguments for which no
default value is specified are required, and either failing to supply the
argument or supplying an undef results in an exception.
From a quick look, this used to be the behavior for labeled arguments but not
for positional arguments. Now that the conversion of labeled args uses the
same code paths as for positional ones, this check isn't done anymore. I'll
fix it and add some tests.
